KINE UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS

Question:
1. Principles of cell theory
Answer:
• The cell is the smallest structural and functional unit capable of carrying out life processes.
• The functional activities of each cell depend on the specific structural properties of the cell.
• Cells are the living building blocks of all plants and animals organisms.
• The cell is the basic unit of life.
• An organism's structure and function ultimately depend on the collective structural characteristics and
functional capabilities of its cells.
• Because of this continuity of life, the cells of all organisms are fundamentally similar in structure and
function.

Question:
2. how many cells are in human body and how many types
Answer:
There are trillions of cells in the human body classified into around 200 cell types

Question:
3. what are cell types based on
Answer:
based on specific variations in structure and function

Question:
4. Cell common features
Answer:
• Plasma Membrane
• Cytosol
• Nucleus

Question:
5. Cell Structure and Function: Plasma membrane
Answer:
• thin membranous structure that encloses each cell
• composed mostly of lipid (fat) molecules (bilayer)
• studded with proteins
• barrier separates the cell's contents from its surroundings
• selectively control movement of molecules into and out of the cell

Question:
6. Cell Structure and Function: Nucleus

, Answer:
• surrounded by a doublelayered membrane
• houses the cell's genetic material, deoxyribonucleic acid (DNA)
• Serves as a genetic blueprint during cell replication
• Directs protein synthesis

Question:
7. Cell Structure and Function: Organelles:
Answer:
endoplasmic reticulum, golgi complex, lysosomes, peroxisomes, centrioles, mitochondria

Question:
8. what does the endoplasmic reticulum do
Answer:
the endoplasmic reticulum is a fluid filled membranous system that produces lipids and proteins

Question:
9. what are the two parts of endoplasmic reticulum
Answer:
Rough ER and Smooth ER

Question:
10. difference between rough and smooth ER
Answer:
rough ER has ribosomes and smooth ER doesn't

Question:
11. what does rough ER do
Answer:
synthesizes proteins to be secreted to the exterior or to be incorporated into plasma membrane or other cell
components

Question:
12. what does the smooth ER do
Answer:
packages the secretory product into transport vesicles, which bud off and move to the Golgi complex

Question:
13. Cell Structure and Function: Organelles --> Golgi Complexr
Answer:
• consists of a stack of flattened, slightly curved, membrane-enclosed sacs
• closely associated with the ER
• Modifies, packages, and distributes newly synthesized proteins

Question:
14. what are lysosomes
